download audacity -
Audacity: Free Audio Editor and Recorder
install it
in Preferences, goto Quality and change the default sample rate to 22050, and in File Formats change the MP3 bitrate to 32
open an mp3 with audacity...
what i do is:
* select the section you want the ringer to be
* copy it and open a new project in audacity
* paste your selection
* place the cursor at the very beginning of the file and Generate|silence
* trim the silence to 1.25 seconds, so there is some silence at the beginning of the track
* split the stereo track
* make both tracks mono
* export to mp3
After creating your mp3/ringer in the correct format, you can use the following site to upload your ringer.
